EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
Improper neutralization of parameters in Snowflake CLI versions prior to 3.19 allowed unintended SQL execution. An attacker could exploit this by supplying crafted values to vulnerable command paths, causing Snowflake CLI to execute unintended SQL in the context of the user’s Snowflake session. Successful exploitation required crafted values to reach vulnerable parameters, including through socially engineered input, malicious repository configuration, or compromised automation feeding external values into the CLI, and impact is limited by the privileges assigned to the active session. The fix is available in Snowflake CLI version 3.19, and users must manually upgrade.
Affected Products
snowflake clisnowflakeDetection & mitigation playbook
Vendor / applianceDetect
Inventory every snowflake snowflake cli deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the snowflake snowflake cli security patch or hotfix for CVE-2026-13752 on the affected version, following the vendor advisory for your exact build.
Workarounds
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2026-13752 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2026-13752. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-13752 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2026-13752 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
